1) Because God has commanded it. The gospel is to preached to
every creature (Mark 16:15). This is why Calvinists have been at the forefront of
missionary endeavor. The man acknowledged as "the Father of Modern Missions"
was
William Carey, and William Carey was a Calvinist. If a missionary
(strictly speaking) is someone who leaves his homeland to preach the gospel
elsewhere, then John Calvin qualifies as a missionary. Spurgeon said of him:
" John Calvin…is looked upon now, of course, a theologian only, but he was
really one of the greatest of gospel preachers. When Calvin opened the Book and
took a text, you might be sure that he was about to preach "Through grace are ye
saved, and that not of yourselves, it is the gift of God." (MTP 14:216) Even
if we had no other reason, we would still evangelize…because it is a clear
command from God.
2) Because we believe that God has ordained the means
of bringing many sons to glory as well as the end. Hyper-Calvinists believe He
has ordained the end but not the means, non-Calvinists
believe that He has ordained the means but not the end, Calvinists
alone consistently take the balanced view that He has ordained both. If
we don't evangelize, someone else rightly will. Calvinists believe as much in
man's responsibility as they do in God's sovereignty.
3) Evangelism gives Calvinists the glorious opportunity to
praise the God whom they believe unconditionally elected them to salvation. We
love to preach the gospel in all its fullness. Just to recount the old, old
story of Jesus and His love thrills our soul and leads us to praise His name. We
glorify God when we proclaim the gospel. Continue at Colin Maxwell
